BytesRef |
getMax()
Returns the largest term (in lexicographic order) in the field.
|
BytesRef |
getMin()
Returns the smallest term (in lexicographic order) in the field.
|
TermsEnum |
intersect(CompiledAutomaton automaton,
BytesRef bytes)
Returns a TermsEnum that iterates over all terms and
documents that are accepted by the provided
CompiledAutomaton . |
TermsEnum |
iterator()
Returns an iterator that will step through all
terms.

public TermsEnum intersect(CompiledAutomaton automaton, BytesRef bytes) throws java.io.IOException
Terms
CompiledAutomaton
. If the startTerm
is
provided then the returned enum will only return terms
> startTerm
, but you still must call
next() first to get to the first term. Note that the
provided startTerm
must be accepted by
the automaton.
This is an expert low-level API and will only work
for NORMAL
compiled automata. To handle any
compiled automata you should instead use
CompiledAutomaton.getTermsEnum(org.apache.lucene.index.Terms)
instead.
NOTE: the returned TermsEnum cannot seek
.NOTE: the terms dictionary is free to
return arbitrary terms as long as the resulted visited
docs is the same. E.g., BlockTreeTermsWriter
creates auto-prefix terms during indexing to reduce the
number of terms visited.
